dynamic_casts do typechecking. So, if it fails, it returns a NULL-pointer.
AFAIK a C cast would just segfault. But as I donīt check the result of each
dynamic_cast the result is the same :-)

And to be honest: Iīm not using dynamic_casts anymore, but I just donīt want 
to go over all the KPresenter and KWord sources and revert the casts :-)
